691410 ÷ 54 
Our goal is to divide 691410 by 54.

Let's proceed to step 1:
When dividing 6 by 54, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 54

Let's proceed to step 2:
54 can be fit into 69 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 54 from 69 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 54

Going ahead to step 3:
The number 54 fits into 151 2 times, leaving a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 108 from 151 to get 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 54

Step 4:
When dividing 434 by 54, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we take 432 away from 434, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 54

Let's proceed to step 5:
21 divided by 54 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 1280.0
If we subtract 0 from 21, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 54

Going ahead to step 6:
54 goes into 210 3 times with a remainder of 48.
The next digit of our result is 3. 
Result so far: 12803.0
The remainder is 48 after subtracting 162 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
The number 54 fits into 480 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 12803.8
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
If we divide 480 by 54, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 12803.88
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 12803.88, with a leftover of 0.048.
